UNITED STATES PATENT OFFICE CARL SOHGNLANK, OF HAMBURG, GERMANY.

BICYCLE-ALARM.

SPECIFICATION forming part of Letters Patent No. 593,336, dated November 9, 1897.

Application filed August 25,1896- Serial No. 603,859. (No model.)

To all whom it 71mg concern:

Be it known that I, CARL SoHoNLANK, banker, of 14 Holstenplatz, Hamburg, in the Empire of Germany, have invented Improvements in Cycles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to cycles; and it consists, essentially, in that a mechanical musical instrument fixed to the cycle is adapted to be operated by the rotation of the wheel. It is preferable to employ that class of mechanical musical instruments which are provided with rotating circular music-sheets, so that the rotary motion of the wheel can be conveniently transmitted to the music-sheet.

The principle of this invention may be carried out in various ways.

Referring to the accompanying drawings, Figure 1 is a view in side elevation of the front portion of a cycle, to the front fork of which is attached the musical instrument. Fig. 2 is a vertical section through the axle of the wheel. Figs. 3 and 4 are a rear elevation and a side elevation, respectively, of the musical instrument; and Fig. 5 shows the details of the coupling apparatus on a larger scale.

Throughout the views similar parts are marked with like letters of reference.

To the front-wheel fork A there is attached in any suitable manner the mechanical musical instrument B, which comprises in its interior a rotating circular music-sheet 0. By the rotation of the music-sheet O, which is suitably perforated by punching in the usual manner, the reed-comb of the musical instrument is plucked, and thus the piece of music is rendered audible.

In order to cause the musical instrument to play when the cycle is traveling forward and to prevent the musical instrument from playing when the cycle is moving backward, there is provided a coupling apparatus or clutch, which I shall now proceed to describe more fully. This clutch serves to enable the musical instrument to be placed out of operation at will during the forward movement of the cycle-that is to say, to prevent the instrument from playing. On the axle of the front wheel there is arranged, as shown in Fig. 2, a toothed wheel I), with which engages a toothed wheel 0, that is connected to the clutch, so that the toothed wheel 0 will always rotate while the cycle is traveling. The axle of the toothed wheel cis adapted to be rigidly connected by means of the afore said clutch with the axle of the toothed wheel d, which engages with the toothed rim of the upon by the spring f, which has a constant tendency to keep the teeth of the part c in engagement with the teeth of the part c. The bearing 71. is designed for the axle of the small toothed wheel d and is arranged on the bottom plate of the musical instrument B. The axle of the small toothed wheel at is held so as to be incapable of longitudinal movement in this bearing by means of a screw-stud 7a, which takes into a groove 2' in the axle (l.

The ratchet-teeth of the clutch parts 6 and e are arranged in such a manner that when the cycle is moving in a forward direction the rotation of the toothed wheel 0 also produces rotation of the small toothed wheel cl, and consequently also of the circular musicsheet 0; but if the cycle moves in a rearward direction the ratchet-teeth of the clutch parts e e slide over each other, while the sliding disk moves with the clutch part at on the axle of d. Consequently no rotation of the small toothed wheel (1 can take place, and therefore the musical instrument cannot come into operation. I

Now in order to be able to place the musical instrument out of operation at will the following arrangement is provided: As shown in Fig. 3, there is arrangedon the bottom of the musical instrument B a double-armed lever Z m, which takes, with its wedge-shaped head part 41, into the bearing box or sleeve D of the clutch. If, now, the arm m of the double-armed lever Zm be ulled, the wedgeshaped head n of the arm enters the box D and forces with its wedge surface the sliding disk g out of its former positionthat is to say, the teeth of the coupling part e move out of engagement with the teeth of the coupling part c and the toothed wheel 0 runs idly. For the purpose of actuating the doublearmed lever Z m there is connected to the arm m a rod or cord 0, Fig. 1, for instance, which is led to the handle-bars and is there provided with a suitable handle.

What I claim, and desire to secure by Letters Patent of the United States, is

In a cycle, the combination with one of the wheels thereof, of a mechanical musical in- In witness whereof I have hereunto set my 20 hand in presence of two Witnesses.
